“…A lot of attention has been devoted in recent years to on-chip hybrid devices where plasmonic nanoantennas have been integrated with standard silicon nitride Si 3 N 4 photonic waveguides. [12][13][14][15][16][17][18][19][20] The transparency of silicon nitride extends towards the visible, thus making it an ideal platform for observing plasmon spectroscopy in the visible and near IR, i.e. the spectral range of interest for plasmonic nanostructures.…”

Plasmonics is a mature scientific discipline which is now entering the realm of practical applications. Recently, significant attention has been devoted to on-chip hybrid devices where plasmonic nanoantennas are integrated in standard Si3N4 photonic waveguides. Light in these systems is usually coupled at the waveguide apexes by using multiple objectives and/or tapered optical fibers, rendering the analysis of spectroscopic signals a complicated task. Here, we show how by using a grating coupler and a low NA objective, quantitative spectroscopic information similar to standard dark-field spectroscopy can be obtained at the single-nanoparticle level. This technology may be useful for enabling single-nanoparticle studies in non-linear excitation regimes and/or in complex experimental environments, thus enriching the toolbox of nanophotonic methods.

“…However, it is still a great challenge to focus a single propagating photon into a single plasmonic nanostructure efficiently due to the huge scale mismatch among photons, metallic nanostructures and molecules. To realize the excitation of LSPs, so far various methods had been proposed, such as prism coupling [14,15], objective lens (free-space excitation) [16], silicon on insulator waveguides [17], and tapered fibers [18,19]. Among these methods, optical tapered fibers with subwavelength diameter are particularly promising in view of their highly efficient LSPs excitation.…”

A simple tapered fiber based photonic-plasmonic hybrid nanostructure composed of a thin tapered fiber and a pseudoisocyanine (PIC)-attached Au-coated tip was demonstrated. Using this simple hybrid nanostructure, we succeeded in observing two-photon excited fluorescence from the PIC dye molecules under a weak continuous wave excitation condition. From the results of the tip-fiber distance dependence and excitation polarization dependence, we found that using a thin tapered fiber and an Au-coated tip realized efficient coupling of the incident light (~95%) and LSP excitation at the Au-coated tip, suggesting the possibility of efficiently inducing two-photon excited fluorescence from the PIC dye molecules attached on the Au-coated tip. This simple photonic-plasmonic hybrid system is one of the promising tools for single photon sources, highly efficient plasmonic sensors, and integrated nonlinear plasmonic devices. 5263-5276 (1997). 36.

“…Our best fabrication result was published in a conference paper [Conf 23], but no journal publication has been written. During our attempts, however, another group published the same geometry, managing to show and measure the expected resonances [235][236][237]. To date we are attempting to replicate such published works, but have not yet succeeded.…”
